Don't know if this is what you're looking for. These are the insides of the original rear interior panels from my '72 Challenger, SBD 8/17/1971. Not sure what that date would be nor the writing below it or the "2" on the other panel.

1972 Dodge Challenger Rallye 340, AT, Code TB3=Super Blue, SBD=8/17/1971. Yes, a Rallye without the fender louvers from the factory because of the body side molding option.
